Title: A method and an apparatus for controlling a video cassette recorder
IPC: G11B27/34
Filed: 1988-03-25
Abstract: A method and an apparatus for assembling, editing 
and producing a production video cassette from a source 
video cassette without timing signal recorded thereon 
is disclosed. The source video cassette is initially 
dubbed onto a dub cassette with timing signals recorded 
thereon. The dub cassette is edited and assembled, 
using the timing signals recorded thereon. Using the 
sync count of the original source cassette, the timing 
signal of the desired video scene is correlated with 
the sync field count of the source video cassette. A 
production cassette is made from the source cassette 
without the timing signal. The present invention also 
discloses assembling, editing and viewing a video 
cassette having timing signals associate recorded 
thereon. The cassette recorder is operated on based 
upon the performance characteristics which were 
predetermined. The assembling and editing of each of 
the video cassettes is done to form the video 
production. The video production is then viewed by 
activating the search and playback capability of the 
video cassette recorder based upon the performance 
characteristics of the cassette recorder. Finally, an 
audio/video controller system is disclosed where a 
plurality of electrically connectable units is in 
communication with one another based upon a digital 
control bus controlling an analog video bus and an 
analog audio bus.

Title: Apparatus for detecting heart characteristics using electrical stimulation
IPC: A61N1/39
Filed: 1988-06-10
Abstract: Apparatus is described for determining ventricular 
fibrillation threshold (VFT), as a measure of electro­
cardiac stability. Input from ECG electrodes (10) and 
optionally also a blood pressure sensor (20) are digitised 
and fed to a data processing unit (50) that controls the 
operation of a unit (60) for generating specifically coded 
pulses used to stimulate the heart. The data processing 
unit (50) adjusts time location and amplitude of the coded 
pulses relative to a series of pacing pulses, in order to 
induce anomalous multiple extrasystoles or ventricular 
tachycardia, the characteristic ECG waveforms being 
identified by the apparatus and the data processing unit 
(50) instructing the signal generating unit (60) to stop 
stimulation without ventricular fibrillation occurring. The 
data processing unit is set up to calculate VFT using the 
amplitude of pulse needed to induce ME/VT, and display the 
calculated VFT value.

Title: Apparatus and method for measuring the signal-to-noise ratio
IPC: H04L27/00
Filed: 1988-09-23
Abstract: A signal source which provides a carrier signal 
(31) having a precisely set signal-to-noise ratio is 
provided. The carrier signal (31) and its sideband 
noise components (33) are attenuated below the 
equivalent thermal noise floor (35) of an attenuator 
(13). The attenuated carrier signal (31) and the 
equivalent thermal noise floor (35) are then amplified 
in an amplifier (15) having a known noise figure to 
produce a composite carrier signal having a usable power 
level and a precisely known signal-to-noise ratio. 
Since the equivalent thermal noise floor (35) is a 
function only of temperature, the desired carrier 
signal-to-noise ratio may be set by setting the power 
level of the carrier signal (31) and knowing the noise 
figure of the amplifier (15).

Title: Interface charge enhancement in delta-doped heterostructure
IPC: H01L29/812
Filed: 1988-10-05
Abstract: Interface carrier density for a selectively doped heterostructure 
(31, 32, 34) in a semiconductor device such as a field effect transistor 
is increased by forming a delta-doped channel layer (33) in close 
proximity to a heterointerface (40) and conduction channel (39). 
In this structure, two quantum mechanical systems (a planar sheet of 
charge carriers and the heterointerface) cooperate to reduce a selected 
barrier thickness below the thickness of an undoped semiconductor spacer 
layer (32) separating the two systems.  
     The delta-doped layer (33) can be grown between the spacer layer 
(32) and the doped semiconductor donor layer (34), but it can as well be 
grown within the spacer layer (32) or within a semiconductor quantum 
well layer (63) grown over the spacer layer (32).

Title: Photoelectric adjusting method and device for automatic computer-based positioning of printing stencils for a rotary screen printing press
IPC: B41F33/00
Filed: 1990-03-20
Abstract: The method and the device based thereon for automatic computer-based positioning of the printing stencils (1) for a rotary screen printing press with optoelectronic scanning of printing marks of different configurations applied to the stencils, provision is made according to the invention for the use of an optical measurement route (2, 11, 12) which penetrates the hollow cylinder wall of the respective printing stencil (1). The electric signal pattern is read into a computer which recognises the printing mark pattern on the basis of a preprogrammed logic and provides control commands to servomotors (4[X], 5[Y]) for the axial and rotational adjustment of the respective printing stencil. The underlying measurement principle has the advantage that the measurement is independent of the surface contrast of the stencil and any engraving faults will have no effect. Furthermore, different stencil diameters can be used without readjusting the measurement route. <IMAGE>
